I looked all over for an app to get the volume back on my Galaxy tab 2 10.1 after the 4.2.2 update killed it.
This is the only one I found that works!
I can actually watch a movie on my tablet again, from 3 to 5 feet away and still hear it.
Thanks for this!

1. Find the folder ViPER4Windows in C:\Program Files
2. right click in the ViPER4Windows folder and go to propierties
3. find security tab
4. in group or users name box, edit permission to full access for each user there (system, administrator, users…).
5. Apply and Close

Open Viper, modify the config as you like, minimized viper app and the error should go now.

It worked fine untill i did an OTA Update of my LG G2 (D802) if i wanna hear musik with the LG musik player the driver is not processing. Iam using the ViPER4Android XHiFi. It would be nice if you could get it to work … i like this player more than the poweramp player

Hi from Brazil! I’m very impressed with sound quality of V4a and V4w. Congrats! I have a question about V4W: Is possible to control sound effects using API or another way than V4W’s control panel?
I have a HTPC with XBMC, that doesn’t have an equalizer or any kind of DSP. So I’d like to create a screen in my XBMC to control sound effects. Is it possible?

Theres a problem with V4W. Everytime I apply settings and go to minimize or close I get an error “unable to access localsettings.bin” or something similar, and the program completely forgets the settings I set when I open it again. Me and my friends all have this problem: OS: Win7SP1 X64 & Win8.1 Pro X64 & Win8.1 X64

Hi. GREAT THANKS for the works you have done. This thing is FABULOUS. This is the only reason for me to root my device for every firmware updates. Anyway, I am really curious that am i the only one who feels that while “Haas”(differential) effect kicks off, the output balance is a bit to the left. it was since (ver. 2.3.1.3). It has been better in the latest version but still i would like to set the settings in the app to 0.45 : 0.55 to be perfect but such option is not available as you know. I have tried to discuss this matter with the Korean users of Viper in (http://www.matcl.com/) only few had agreed but still not sure if its some particular devices or its my ears that is causing this problem. i just hope that it could be looked over. Thanks again.

Hello, I have installed viper4W. In windows 7 ultimate x64.
I have sound blaster audigy live 24 Bit. card, but I. Don’t hear nothing effect. I check up SB audigy and Realtek speakers in viper4A configuration, but I don’t get nothing effect.

viper4android not work with this version viperone 8.0 in the previous version viperone 7.2 works correctly and also ask them how to remove or reduce white background sound produced by amplifying the audio.
Greetings and thanks

Ehy Devs, great job! Just a tip: the link you’ve provided for the latest Android version (2.3.4.0) in useless if posted like you did (you put in the also the .zip part of the link, but this way the download starts and fails instantly because Mediafire did not authorized them). To solve the problem, remove the last part of the link (just till tge slash) or use (it’s your link already trimmed). Keep going!

Viper4Android FX works like charm! i’ve been searching for apps like this but not impressive enough. This is the best audio effect i ever found in this world… thx viper!!! viper audio on windows? wow!!! cant wait to try it….!

Viper4Android is absolutely the BEST SOUND MOD AVAILABLE FOR ANDROID PERIOD. Anything you can get on the Play Store can’t even come close to this. The INREDIBLY CLEAN BASS W/OUT LOSING THE DEPTH. SAME FOR THE MIDS AND HI’s. I WILL NOT HAVE A PHONE WITHOUT THIS MOD. PERIOD.

I am unable to install the drivers in ViPER4Android xperia zq android 5.1.1, the following message appears,
install failed: The busybox installation found on your device does not work. This usually means you installed a wrong or broken busybox. V4A needs Stericson’s busybox to work. If you are sure you installed the proper busy box, then please confirm your device has been completely rooted. OK
